BioLargo Technology Being Studied By University of Hawaii for Effectiveness to Treat Beach Contamination

BioLargo, Inc. (OTCBB:BLGO) has announced that the University of Hawaii recently commenced a nine-month study of CupriDyne(TM), the centerpiece of the company's BioLargo technology, and its effectiveness as part of a solution to remediate beach contamination.

The study is being conducted by Dr. Roger Fujioka at the University of Hawaii's Water Resources Research Center, at the request of the State's Department of Health and the City and County of Honolulu. These agencies have expressed interest in the results of the study and CupriDyne's potential to help remediate beach contamination. The study will evaluate the effectiveness of CupriDyne to disinfect multiple microorganisms commonly found at contaminated beaches, including E. coli, using standards established by the United States Environmental Protection Agency.

"We welcome the opportunity to work with Dr. Fujioka and the team of experts at the University of Hawaii to advance the commercialization of our BioLargo technology," said Dennis Calvert, BioLargo's President and Chief Executive Officer. "We believe that our environmentally friendly technology has the potential to represent a significant advancement in helping protect the beach environment."

Dr. Fujioka stated, "At this time there is no effective and feasible treatment for sand contamination, and all affected states within the U.S., including Hawaii, are looking for an effective and environmentally friendly solution."

Laurence K. Lau, Deputy Director for Environmental Health at the State of Hawaii Department of Health, said, "We look forward to BioLargo and the University of Hawaii working together to help protect the public and our beaches."
